What Does Pentium III Mean?

The Pentium III model, introduced in 1999, represents Intel’s 32-bit x86 desktop and mobile microprocessors in accordance with the sixth-generation P6 micro-architecture.


The Pentium III processor included SDRAM, enabling incredibly fast data transfer between the memory and the microprocessor. Pentium III was also faster than its predecessor, the Pentium II, featuring clock speeds of up to 1.4 GHz. The Pentium III included 70 new computer instructions which allowed 3-D rendering, imaging, video streaming, speech recognition and audio applications to run more quickly.

Techopedia Explains Pentium III

The Pentium III processor was produced from 1999 to 2003, with variants codenamed Katmai, Coppermine, Coppermine T and Tualatin. The variants’ clock speeds varied from 450 MHz to 1.4 GHz. The Pentium III processor’s new instructions were optimized for multimedia applications called MMX. It supported floating-point units and integer calculations, which are often required for still or video images to be modified for computer displays. The new instructions also supported single instruction multiple data (SIMD) instructions, which allowed a type of parallel processing.

Other Intel brands associated with the Pentium III were Celeron (for low-end versions) and Xeon (for high-end versions).
